AUGUSTUS is the largest trial in this high-risk patient population
requiring both anticoagulant and antiplatelet therapies

PRINCETON, N.J. & NEW YORK–(BUSINESS WIRE)– The Bristol-Myers
Squibb–Pfizer
Alliance today announced results from the Phase 4 AUGUSTUS trial
evaluating Eliquis® (apixaban) versus vitamin K
antagonists (VKAs) in patients with non-valvular atrial fibrillation
(NVAF) and recent acute coronary syndrome (ACS) and/or undergoing
percutaneous coronary intervention (PCI). Results show that in patients
receiving a P2Y12 inhibitor with or without aspirin (antiplatelet
therapies), the proportion of patients with major or clinically relevant
non-major (CRNM) bleeding at six months was significantly lower for
those treated with Eliquis compared to those treated with a VKA
(10.5% vs. 14.7%, respectively; hazard ratio [HR]: 0.69, 95% confidence
interval [CI]: 0.58-0.81; p-superiority<0.001). These data are featured
as a late-breaking oral presentation at the American College of
Cardiology’s (ACC) 68th Annual Scientific Session 2019 in New Orleans,
LA (Abstract 405-08) and simultaneously published in the New England
Journal of Medicine.

AUGUSTUS, which evaluated 4,614 patients, is an open-label, prospective,
randomized clinical trial designed to assess two independent hypotheses:

Whether or not Eliquis 5mg* twice daily is non-inferior or
superior to VKAs for the outcome of major or CRNM bleeding, as defined
by the International Society on Thrombosis and Haemostasis (ISTH), in
patients with NVAF and recent ACS and/or undergoing PCI with planned
concomitant antiplatelet therapy (a P2Y12 inhibitor with or without
low-dose aspirin).

Whether or not single antiplatelet therapy with a P2Y12 inhibitor is
superior to dual antiplatelet therapy with a P2Y12 inhibitor and
low-dose aspirin for the outcome of ISTH major or CRNM bleeding in
patients with NVAF and recent ACS and/or undergoing PCI and planned
concomitant anticoagulant therapy (either Eliquis 5mg* twice
daily or VKA).

*2.5mg twice daily if patients met two or more of the following
dose-reduction criteria: age ? 80 years, weight ? 60 kg or creatinine ?
1.5mg/dL (133 micromol/L).

Independent of the Eliquis versus VKA comparison, results also
showed that in patients receiving a P2Y12 inhibitor and an
anticoagulant, the proportion of patients with major or CRNM bleeding at
six months was significantly higher for those receiving aspirin compared
to those receiving placebo (16.1% vs. 9.0%, respectively; HR: 1.89, 95%
CI: 1.59-2.24; p<0.001).

Please note that Eliquis increases the risk of bleeding compared
with placebo and can cause serious, potentially fatal, bleeding. Please
see below for Important Safety Information, including information from
the APPRAISE-2 clinical trial that was terminated early due to higher
rates of bleeding for apixaban compared to placebo in post-ACS patients
without an indication for oral anticoagulant.1

The investigators also analyzed the pre-defined secondary composite
outcomes of death or hospitalization and death or ischemic events
(including myocardial infarction, stroke, definite or probable stent
thrombosis or urgent revascularization). At six months, patients
receiving a P2Y12 inhibitor with or without aspirin who were treated
with Eliquis had lower rates of death or hospitalization (23.5%
vs. 27.4%, respectively; HR: 0.83, 95% CI: 0.74-0.93; p=0.002) and
similar rates of death or ischemic events (6.7% vs. 7.1%, respectively;
HR: 0.93, 95% CI: 0.75-1.16; p=NS) compared to those assigned to VKA.
Patients receiving a P2Y12 inhibitor and an anticoagulant who were
treated with aspirin had similar rates of death or hospitalization
(26.2% vs. 24.7%, respectively; HR: 1.08, 95% CI: 0.96-1.21; p=NS) and
similar rates of death or ischemic events (6.5% vs. 7.3%, respectively;
HR: 0.89, 95% CI: 0.71-1.11) compared to those assigned to placebo.

Atrial fibrillation is the most common arrhythmia in the world,
affecting an estimated 33 million people in 2010.2 It is
estimated that approximately 20-to-30 percent of people with atrial
fibrillation also have concomitant coronary artery disease,3,4
which may result in ACS or require PCI. Additionally, five-to-ten
percent of patients who undergo PCI have atrial fibrillation.5,6,7,8
While oral anticoagulants and dual antiplatelet therapy help reduce the
risk of stroke and recurrent ischemic events, respectively, the
combination leads to an increased risk of bleeding. Therefore,
additional research has been needed to help inform antithrombotic
regimens available for these high-risk patients.

“Advancing care for patients at risk for stroke due to non-valvular
atrial fibrillation is a key focus of the BMS-Pfizer Alliance,” said
Christoph Koenen, M.D., Head of Cardiovascular Development,
Bristol-Myers Squibb. “The AUGUSTUS trial represents our ongoing
commitment to understanding anticoagulation among higher-risk patients.”

About AUGUSTUS

AUGUSTUS is an international, multicenter, open-label, randomized
controlled trial with a two-by-two factorial design to compare Eliquis
(apixaban) with vitamin K antagonists (VKAs) and aspirin with placebo in
4,614 patients with non-valvular atrial fibrillation (NVAF) and recent
acute coronary syndrome (ACS) and/or undergoing percutaneous coronary
intervention (PCI), and are receiving a P2Y12 inhibitor for at least six
months. The treatment regimen comparing Eliquis with VKA was
open-label; however, the regimen comparing aspirin with aspirin placebo
was double blind. Patients were evaluated for eligibility during their
ACS and/or PCI hospitalization. 37.3 percent of patients included in the
study had ACS undergoing PCI, 23.9 percent of patients had
medically-managed ACS and 38.8 percent of patients underwent elective
PCI. The primary outcome is the composite of major or clinically
relevant non-major (CRNM) bleeding defined by the International Society
on Thrombosis and Haemostasis (ISTH).9 A key secondary
outcome is the composite of death or first hospitalization. Other
secondary outcomes include the composite of death or ischemic events
(myocardial infarction, stroke, definite or probable stent thrombosis or
urgent revascularization). AUGUSTUS was designed to be a safety study
and did not include a primary efficacy endpoint.

About Atrial Fibrillation

Atrial fibrillation (AF) is the most common type of arrhythmia, or
irregular heartbeat. Nonvalvular atrial fibrillation (NVAF) refers to
cases in which the AF occurs in the absence of rheumatic mitral valve
disease, a prosthetic heart valve, or mitral valve repair. It was
estimated that in 2014, 6.4 million people in the U.S. and in 2010, over
six million individuals in Europe, had AF. The lifetime risk of AF is
estimated to be approximately 25 percent for individuals 40 years of age
or older. One of the most serious medical concerns for individuals with
AF is the increased risk of stroke, which is five times higher in people
with AF than those without AF. Additionally, AF-related strokes tend to
be more severe than other strokes with an associated 30-day mortality
rate of 24 percent and a 50 percent likelihood of death within one year.

About Acute Coronary Syndrome

Acute coronary syndrome (ACS) is a term used to describe situations in
which the blood supplied to the heart muscle is suddenly blocked, and
includes myocardial infarction (MI), also known as a heart attack, and
unstable angina (sudden, severe chest pain that typically occurs when a
person is at rest). ACS affects an estimated 1.4 million people in the
U.S. and an estimated 1.38 million people in Europe. ACS is a
subcategory of coronary artery disease (CAD), the most common type of
cardiovascular disease. Cardiovascular diseases are the number-one cause
of death worldwide. According to the World Health Organization, CAD
alone resulted in 7.4 million deaths during 2012.

About Percutaneous Coronary Intervention

Percutaneous coronary intervention (PCI), also known as coronary
angioplasty, is a procedure used to open blocked or narrowed coronary
arteries. Angioplasty also is used as an emergency procedure during a
heart attack. According to the Centers for Disease Control and
Prevention, there are approximately 500,000 PCIs performed annually in
the U.S. alone.

About Eliquis

Eliquis (apixaban) is an oral selective Factor Xa inhibitor. By
inhibiting Factor Xa, a key blood clotting protein, Eliquis
decreases thrombin generation and blood clot formation. Eliquis is
approved for multiple indications in the U.S. based on efficacy and
safety data from multiple Phase 3 clinical trials. Eliquis is a
prescription medicineindicated to reduce the risk of stroke and
systemic embolism in patients with nonvalvular atrial fibrillation
(NVAF); for the prophylaxis of deep vein thrombosis (DVT), which may
lead to pulmonary embolism (PE), in patients who have undergone hip or
knee replacement surgery; for the treatment of DVT and PE; and to reduce
the risk of recurrent DVT and PE, following initial therapy.

Premature discontinuation of any oral anticoagulant, including
ELIQUIS, increases the risk of thrombotic events. If
anticoagulation with ELIQUIS is discontinued for a reason other
than pathological bleeding or completion of a course of therapy,
consider coverage with another anticoagulant.

(B)

Epidural or spinal hematomas may occur in patients treated with
ELIQUIS who are receiving neuraxial anesthesia or undergoing
spinal puncture. These hematomas may result in long-term or
permanent paralysis. Consider these risks when scheduling patients
for spinal procedures. Factors that can increase the risk of
developing epidural or spinal hematomas in these patients include:

•

use of indwelling epidural catheters

•

concomitant use of other drugs that affect hemostasis, such as
nonsteroidal anti-inflammatory drugs (NSAIDs), platelet
inhibitors, other anticoagulants

•

a history of traumatic or repeated epidural or spinal punctures

•

a history of spinal deformity or spinal surgery

•

optimal timing between the administration of ELIQUIS and
neuraxial procedures

•

is not known

Monitor patients frequently for signs and symptoms of
neurological impairment. If neurological compromise is noted,
urgent treatment is necessary.

Consider the benefits and risks before neuraxial intervention
in patients anticoagulated or to be anticoagulated.

Increased Risk of Thrombotic Events after Premature
Discontinuation: Premature discontinuation of any oral
anticoagulant, including ELIQUIS, in the absence of adequate
alternative anticoagulation increases the risk of thrombotic events.
An increased rate of stroke was observed during the transition from
ELIQUIS to warfarin in clinical trials in atrial fibrillation
patients. If ELIQUIS is discontinued for a reason other than
pathological bleeding or completion of a course of therapy, consider
coverage with another anticoagulant.

Concomitant use of drugs affecting hemostasis increases the risk
of bleeding, including aspirin and other antiplatelet agents,
other anticoagulants, heparin, thrombolytic agents, SSRIs, SNRIs,
and NSAIDs.

Advise patients of signs and symptoms of blood loss and to report
them immediately or go to an emergency room. Discontinue ELIQUIS
in patients with active pathological hemorrhage.

The anticoagulant effect of apixaban can be expected to persist
for at least 24 hours after the last dose (i.e., about two
half-lives). An agent to reverse the anti-factor Xa activity of
apixaban is available. Please visit www.andexxa.com
for more information on availability of a reversal agent.

Spinal/Epidural Anesthesia or Puncture: Patients treated with
ELIQUIS undergoing spinal/epidural anesthesia or puncture may develop
an epidural or spinal hematoma which can result in long-term or
permanent paralysis.

The risk of these events may be
increased by the postoperative use of indwelling epidural catheters or
the concomitant use of medicinal products affecting hemostasis.
Indwelling epidural or intrathecal catheters should not be removed
earlier than 24 hours after the last administration of ELIQUIS. The
next dose of ELIQUIS should not be administered earlier than 5 hours
after the removal of the catheter. The risk may also be increased by
traumatic or repeated epidural or spinal puncture. If traumatic
puncture occurs, delay the administration of ELIQUIS for 48 hours.Monitor
patients frequently and if neurological compromise is noted, urgent
diagnosis and treatment is necessary. Physicians should consider the
potential benefit versus the risk of neuraxial intervention in ELIQUIS
patients.

Prosthetic Heart Valves: The safety and efficacy of ELIQUIS
have not been studied in patients with prosthetic heart valves and is
not recommended in these patients.

Acute PE in Hemodynamically Unstable Patients or Patients who
Require Thrombolysis or Pulmonary Embolectomy: Initiation of
ELIQUIS is not recommended as an alternative to unfractionated heparin
for the initial treatment of patients with PE who present with
hemodynamic instability or who may receive thrombolysis or pulmonary
embolectomy.

ADVERSE REACTIONS

The most common and most serious adverse reactions reported with
ELIQUIS were related to bleeding.

TEMPORARY INTERRUPTION FOR SURGERY AND OTHER INTERVENTIONS

ELIQUIS should be discontinued at least 48 hours prior to elective
surgery or invasive procedures with a moderate or high risk of
unacceptable or clinically significant bleeding. ELIQUIS should be
discontinued at least 24 hours prior to elective surgery or invasive
procedures with a low risk of bleeding or where the bleeding would be
noncritical in location and easily controlled. Bridging
anticoagulation during the 24 to 48 hours after stopping ELIQUIS and
prior to the intervention is not generally required. ELIQUIS should be
restarted after the surgical or other procedures as soon as adequate
hemostasis has been established.

Although clarithromycin is a combined P-gp and strong CYP3A4 inhibitor,
pharmacokinetic data suggest that no dose adjustment is necessary with
concomitant administration with ELIQUIS.

Combined P-gp and Strong CYP3A4 Inducers: Avoid concomitant use
of ELIQUIS with combined P-gp and strong CYP3A4 inducers (e.g.,
rifampin, carbamazepine, phenytoin, St. John’s wort) because such
drugs will decrease exposure to apixaban.

Anticoagulants and Antiplatelet Agents: Coadministration of
antiplatelet agents, fibrinolytics, heparin, aspirin, and chronic
NSAID use increases the risk of bleeding. APPRAISE-2, a
placebo-controlled clinical trial of apixaban in high-risk post-acute
coronary syndrome patients treated with aspirin or the combination of
aspirin and clopidogrel, was terminated early due to a higher rate of
bleeding with apixaban compared to placebo.

PREGNANCY CATEGORY B

There are no adequate and well-controlled studies of ELIQUIS in
pregnant women. Treatment is likely to increase the risk of hemorrhage
during pregnancy and delivery. ELIQUIS should be used during pregnancy
only if the potential benefit outweighs the potential risk to the
mother and fetus.
